A processor is a kind of specialized microchip. Its function is to accelerate, address, solve or prepare data depending on the application. Basically, a processor is a powerful calculator: It receives a certain amount of data, oriented in binary pattern 0 and 1 and has the function of responding to that volume, processing the information based on instructions stored in its internal memory.
The term “electronic brain” is far from classifying and summarizing the operation of a processor. However, the Control Unit is the closest to a brain within the processor. This controller defines the operating and ordering order of the various processor tasks.
Importance of Clock
Having more or less Hertz means how much the processor exchanges data with the system. The 2.0 GHz processor can perform 2 billion cycles per second.
The clock circuit, which measures the cycles and guides the pace of the information exchange flow in the processor, is one of the main criteria for establishing the processor speed. It is worth noting, however, that other points enter this account, such as memory interface, cache quantity, architecture, among others.
There are several types of processors and each type of application requires a certain type of processor. This is the case with our computers, which use x86.
Compact devices with fewer types of applications use different types of processors. The cell phone, regardless of the level of sophistication, uses a SoC processor ( an acronym for System on a Chip: system on a chip). This means that the processor in question adds several other features, such as radio chip, connectivity, graphics processor, and more.
Basically, any chip that controls some hardware is a processor. It receives data, addresses it, and returns it processed. A network card, a Bluetooth adapter and even a pen drive have controllers.
GPUs and parallelism
This explains why newer supercomputers are built by adopting GPU clusters.
Although they are not a match for logical processing of CPUs, graphics processors are ideal for a large volume of data.
